Application September 20, 1947, Serial No. 775,221

10 Claims. (Cl. 15-129) This invention relates to a dish and like washing apparatus. A

rThe chief object of the present invention is to provide apparatus that will selectively wash and rinse, the washing being accomplished by a soap and/or detergent water solution, the rinsing being of soapless character, the washing and rinsing being accomplished with hot Water, cold water, or warm Water as desired or required.

The chief feature of the present invention residesl in providing a water and a detergent solution supply to a fountain type brush and the like, iinger control of which utilizes the water pressure for detergent supply for Washing purposes when desired.

Another feature resides in the brush unit embodied in this invention.

A further feature resides in the detergent reservoir and the supply therefrom to the said brush.

Still another feature resides in the incorporation of the present invention in a combination mixing spout xture with diversion valve control.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings,

Fig. 1 is a perspective view of a kitchen sink fixture or mixing unit of diversion valve type with which is associated the detergent reservoir, pump means, the handle type brush and its attached control all embodying the invention.

Fig. 2 is a. vertical sectional view through the detergent reservoir and associated parts, the cover being omitted.

Fig. 3 is a longitudinal sectional view of the handle type brush and its control.

Fig. 4 is a transverse sectiona1 view taken on line 4-4 of Fig. 3 and in the direction of the arrows.

In Fig. 1 of the drawings I0 indicates a mixing chamber fixture unit connected at II and I2 to hot and cold water pressure supplies controlled by valves I3 and I4 respectively for regulating the amount discharged from spout I5 and the temperature thereof as well understood in the art. I6 indicates a control that operates through an eccentric pin and slot a diversion valve means I6a, generally known in the art as a diverter valve, which when disposed in one position effects mixing chamber discharge from spout I5 and when disposed in an opposed position effects spout cut-off and diversion oi the water to another outlet such as indicated at 20. Herein, see Fig. 2, ISb indicates the eccentric pin operable by handle shaft I6 (see Fig. 1) and I 6c indicates the cooperating slot associated with valve |68.

In Fig. 1, I'i indicates a chamber forming housing or reservoir having tiltable lid or cover I8, soap solution outlet I9 and Water outlet 20. Passage 2I in the base of said housing has an intake 22 suitably connected to or communicating with the mixing chamber I0 and controlled by diverter Valve control I6a.

Passage I has a branch 23 leading to a chamber 25 closed by diaphragm 25 normally subject to a spring 26 disposed to position the diaphragm, when not subject to iiuid pressure, as illustrated in Fig. 2.

Chamber 24 is formed as a part of partition 21 near the bottom of chamber I'I. Member 28 forms with the diaphragm a pump chamber and includes stem 29 threaded at 36 to take closure 3l whereby the force of spring 26 can be adjusted to the supply pressure in passage 2| when the full pressure of the mixing chamber I0 is diverted and is applied thereto.

Member 28 forms pump or detergent chamber 32 with the diaphragm 25. It has check valve controlled ports 33 and 34 controlled by checks 35 and 36 respectively. The former serves as an intake from the soap chamber. The latter serves as a discharge from the pump chamber.

When fluid pressure is increased in passage 2| as hereinafter described, the increase in pressure flexes diaphragm 25 in opposition to spring 26 thereby forcing soap solution from chamber 32 past check 36 and through outlet 34 to line 31 connecting to outlet member I9. intake 33 prevents soap solution return to reservoir I'i.

When the fluid pressure is released or decreased in passage 2I the spring 26 returns diaphragm 25 to the position shown in Fig. 2, which return eiiects suction of soap solution into pump chamber 32 through intake 33, soap return from line 3l etc. being prevented by check valve 36.

Thus the diaphragm is actuated as often as the pressure in passage 2l is increased which is as often as the discharge from line 2| is checked or momentarily restricted as now will be described.

Referring to Figs. l and 3, it will be noted that one flexible conduit 38 is connected at one end to handle 39 and at its opposite end to outlet 2U of passage 2I. A second flexible conduit 40 is connected at one end to handle 39 and at the other end to outlet I9.

Check 35 in In Fig. 3 handle 39 includes passages 4I and 42 wherein conduits 38 and 40 are disposed. Handle 39 is longitudinally notched at 43 and disposed therein is member 44 having clamp portion 45 and exposed linger engageable portion 46. Pin 41 or the like pivotally supports the member 44 in the notch of the handle.

When iinger pressure is applied to portion 46, portion 5.5 is depressed restricting the free flow through passage 2tand. conduit 39I thereby building up 'a' pressure in chamber 24 to ex diaphragm 25. When the finger pressure is re; leased, the water pressure returns member 44 to the position shown in Fig. 3 and:y the spring 26 returns diaphragm 25 to the posit'mn shown in Fig. 2. Y

The end of handle 39 is closed: as at 4 3; and; same has two bores 49 and 5l]V with which tubes 38 and 49 connect. A tubular arm 5l terminatesk in a brush head 52 which is hollow and has a petiereteflnleteSeifqrdisehareenuriieses.
